Raspberry PI Zero W - No wireless interfaces found

by vano on Sat Dec 09, 2017 9:43 pm

I recently got R-PI Zero W and MicroSD with Noobs 2.0 https://www.adafruit.com/product/3259 on it from adafruit. I put SD card in and connected the PI to the 5V/2A power source. Once it booted I tried to configure WiFi. When I click on WiFi icon it shows message "No wireless interfaces found":

If I open Network Preferences I see all fields greyed out for both "interface" and "SSID" options:

Then I used SD card from my PI 3 where I have WiFi configured and working but got the same behavior. Even when I set WiFi configurations in /etc/wpa_supplicant/wpa_supplicant.conf file manually, I still cannot get any WiFi network to show up in the taskbar.
The "ifconfig" gives me only loopback network.

Also I cannot seem to get Bluetooth to work. Does this mean that WiFi and Bluetooth hardware has faulted?
If that's the case, how can I exchange my PI Zero W for a fully operational one considering that it's been less than 30 days since I purchased the product?

Try downloading the latest version of the Raspbian OS and run that. NOOBS has had an issue with the wifi on the Zero W.

How about this part that I mentioned:
Then I used SD card from my PI 3 where I have WiFi configured and working but got the same behavior. Even when I set WiFi configurations in /etc/wpa_supplicant/wpa_supplicant.conf file manually, I still cannot get any WiFi network to show up in the taskbar.

If the issue was in software, wouldn't my SD card from PI 3 work on PI Zero W?

Is your SD card the latest version of the OS?

How do I verify whether the OS I have on my SD is the latest?
Here is the output from $ cat /etc/os-release
Code: Select all | TOGGLE FULL SIZE
PRETTY_NAME="Raspbian GNU/Linux 8 (jessie)"
NAME="Raspbian GNU/Linux"
VERSION_ID="8"
VERSION="8 (jessie)"
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
..........

Output of command $ uname -a
Code: Select all | TOGGLE FULL SIZE
Linux raspberrypi 4.1.19+ #858 Tue Mar 15 2016 armv6l GNU/Linux

Assuming that the OS I have on SD is not the latest. Is it expected that SD with OS that works fine on PI 3 may have WiFi and Bluetooth non-operational when used with PI Zero W?

yeah you may need to update to stretch. if you have internet (using an Ethernet adapter) you can, from the command line, run "sudo apt-get update" "sudo apt-get upgrade" and it'll do it for you. Or you can grab the latest NooBs from raspberrypi.org

I formatted SD card and installed latest NOOBS image on it https://www.raspberrypi.org/downloads/noobs/. After that I was able to install latest RASPBIAN on it and connect to Bluetooth and WiFi.
Thanks for the help!
